1. The Defendant’s KRW 19,305,00 for the Plaintiff and KRW 6% per annum from September 1, 2018 to January 15, 2020 for the Plaintiff.

1. The Defendant was awarded a subcontract for the nine-story interior works among the construction works extending the “subsan D building” from C Co., Ltd.

On July 5, 2017, the Defendant entered into an environmental management agreement with the Plaintiff and the Plaintiff on July 5, 2017 with respect to the performance of subcontracted construction works, and “a two-way work agreement with respect to the transportation of necessary materials (such as tin, resort, cement, sand) at the nine-story construction site,” respectively.

Accordingly, from July 5, 2017 to July 25, 2017, the Plaintiff completed the construction waste disposal and mass disposal respectively.

Around July 27, 2017, the Defendant settled the costs of the construction waste disposal work with the Plaintiff and the construction waste disposal cost of KRW 23,100,000 (including value-added tax), and paid the said money in full thereafter.

However, over the settlement of the two-way work costs, the dispute between the plaintiff and the defendant led to the lawsuit in this case.

3. The Plaintiff and the Defendant agreed to calculate the two-way work cost by the personnel expenses of the worker who invested in the work (no dispute).
